As herein shown, the-copy holder includes a base I0 having'an'arm I lextending 'from one end thereof. Thearm H is shown as being in the formof 'an angle iron in cross section, and

'may be secured 'toa desk or tableto hold the copy holder upright. Thearm l'l Yalso forms a pivotal support foran l'operating link and levermechanism indicated generally by 'reference cthara'cter l2, for rotatinga'platen 14. 'step by s ep.

holder frame I5, mounted on said base for vertical extensible movementwith respect thereto. The link and lever mechanism I2 and the mechanismactuated thereby for rotatably moving the platen a line at a time isshown and described in my Patent No. 2,170,161, dated August 22, 1939,and is no part of my present invention, so need not be shown ordescribed in detail herein.

The copy holder frame I5 is shown as being slidablyv mounted on twoupright rods I1-I1 suitably secured to the base I0 at their lower endsand extending upwardly therefrom in parallel relation with respect toeach other. The

upright rods II--II each have slidable engagement with two parallel,vertically spaced lugs I3 and extending forwardly from a back 2| of thecopy holder frame I5. A rib 23 connects the lugs 20-20 together andserves to stiften the copy holder frame I5 and also serves as abutmentmeans for springmeans for moving and holding the copy holder latchingmechanism into an unlatched position, as will hereinafter more clearlyappear as this specification proceeds.

The platen I4 is suitably mounted on a shaft 24, for rotation therewith.The shaft 24 is journaled at its ends in side frame members 25-25 of thecopy holder frame I5. Said shaft extends outwardly from said side framemembers and has knobs 21-21 on its outer ends, to permit turning of theplaten by hand independently of the lever operated actuating mechanismtherefor, when desired. Y Y

A line guide member 29 is spaced forwardly of the copy holder frame I5and is mounted for extensible orv collapsible movement with respect tothe base I0 with the copy holder frame I5. The line guide member 29 -isherein shown as including a cross head-3D having twospaced hollow rodsor sleeves 3I`3 I depending therefrom, adjacent opposite ends thereof,in parallel spaced relation with respect to each other. The sleeves3'I-3I are slidably mounted on parallel spaced rods 33--33 suitablymounted in the base I0 at their lower ends for yieldable movement withrespect thereto, and biased to engage a pressure roll 34 with the platenI4. The pressure roll 34 is herein shown as being rotatably mounted onears 35-35 extending inwardly from the cross head 30, and exertspressure on the paper to hold the paper to the platen I4 sothe paper maybe positively advanced a line at a time, upon progressive turningmovement of said platen.

Referring now in particular to the novel form of the cross head 30,wherein said cross head maintains a sheet of paper in, position so itmay easily be read when the paperlias been released from' the pressureroll 35, the cross head 30 is herein shown as having anl inwardly turnedupper end portion or lip 40. VThe lip 40 is herein shown as extending atright angles to the body of the cross head and engages the lower edge ofthe paper when released from the pressure roller 34 and supported oncopy guides 35 and 31 and trained under an intermediate copy guide 38,as may be 'seen in dotted linesin `Figure 9. The lip 40 of the crosshead 30 thus projects partially over the pressure roll 34 and holds thelower edge of the paper from moving upwardly into such a'position thatthe material thereon cannot readily be seen. This remedies anobjectionable feature of former copy holders in which it is impossibleto read notes or insertions at the bottom ofthe paper without removingthe paper from the copy holder and placing it flat on the desk. `Whilethe lip 40 is herein shown as being turned at right angles with respectto the body of the cross head, said lip need not extend at right angleswith respect to the body of the cross head, but may extend at variousother desired angles or may be of a uniformly curved formation, as longas its lower edge may come into gripping engagement with the lower edgeof the paper when released from the platen 24.

The copyvguides 31 and 38 are mounted on parallel spaced pivoted arms 4I-,4I, secured to a transverse shaft 43, having the c01357 guide 36secured thereto. The shaft 43 is shown as extending beyond the limits ofthe copy holder frame I5 to guide paper wider than said frame, and afree open space is provided between the Vline guide member and theplaten I4 to permit the insertion of sheets of paper therebetween, widerthan the length of the copy holder frame I5.

The copy guide 35 is herein shown as being securedto the transverseshaft 43,l for turning movement therewith and is restrained frommovement by the legs 4444 .of a U-shap'ed spring 45. Thelegs 44444engage opposite sides of the copy guide 36 and restrain the arms 4'I-4Iand copy guides 31 and 38 from movement, and yieldably hold said armsand the copy guides carried thereby in the upwardly extended position nshown in Figures 3 and 9.

A means is provided to hold the line guidemeinber and pressure roll 34out of engagement with the platen I4 and to align the paper with thecross head 29. Said means,` as shown, includes two spaced arms 46-46secured to and extending from a rod 41. The rod 41 is journaled adjacentits ends in the side frame members 25-25 of the copy holder frame I5. Atorsion spring 49 encircles the rod 4.1. One end of said spring issecured to the rod 41, and the opposite end thereof engages the topsurface of the lug I9 and urges the rod 41 to move in a direction tohold the lever arms 46--46 in a downwardly extended position out o fengagement with the sleeves 3 I 3I of the line guide Vmember 29. `Whenthe arms 45-48 are turned outwardly, by grasping .with the hand, to theposition shown in Figure 3, the line guide 29 and pressure roller 34 aremoved away from the copy holder frame l5 and platen I4 in an obviousmanner. The strength of the spring 49 is such that the arms 46-46 wereretained in the outwardly extending position shown in Figure 3 by thefriction between the ends of said arms and the sleeves 3I-3I,V and saidarms are only moved in the downwardly extended position shown in Figure4 by the spring 49, when positively released from the sleeves 3I-3I byhand.

It may here be seen that when the arms 46-46 are in the horizontallyextended position shown in Figure 3, moving the pressure roll away fromthe platen I4, said arms not only form a means for readily inserting thepaper in the copy holder, but also form an accurate aligning means,bottoming and aligning the sheet of paper being copied.

Referring now to the novel latching and release means of my invention,for latching and releasing the copy holder frame I5 and line guide 29, aVdetent rod is provided to lock the copy holder frame in an extendedposition. The detent rod 58 is pivotally mounted in the side framemembers 25-25 Vand isvurged by a torsion spring 5I to pivot in adirection to come into engagement with recessed portions 52-52 of thesupport and guide rods I1-I1. The spring 5I encircles the detent rod 53and is secured thereto at one of its L ends. A-Theother-endofsaid-;spring engages the ribV 23:.and urges the detent vrodto .pivot .in ya countercloclrwise direction. VA winged iinger grip 53:is shown .as lloeingvsecured to the outer end, of said-detent rod, forturning said; detentrrod againstsaid .spring .into a released position.The detent rod 5I), Aasrherein 'shown,fhas-two .recessed portions formedtherein in registry with the guide rod .Ilo-I1, the -inner sides ofwhich are-ilat, as indicated by reference character 54. The flat innersides-54-54of the detent. rod'are in alignment with thejouterperipheryofthefsupport and guide rods -I 'If- I 'I when -saidV flat sides are in avertical position; Thus, when the detent rod 50 is turned in a positionbythe fingeligrip 53 to position thelat sides-5ll- 5ll thereof :in.alignment withthe peripheryof :thelsupportfandfguide ro'dsII'-I-'I, theCopyholderoframe I5 may freely move along` said rodl into 1a lcollapsedposition.

` While fthe rod -50 -is-` shown'as having two frecessed portions, -itshould be-understoo d that the entire rod may be'flattened along'` itslength, if desired.

Asthe.copyholderfframe. I5 is extended along thesupportand'guide rodsrl'I-I 'I and the detent rod. 5 5 comes intol registry ywithfthe recesses524-52,y the torsionsprng 5I will; rapidly turn said detentrod to engageAftheperiphery-thereof with the recessed portions52-52 yof -the lsupportand guide rods` Ill-I1, locking the copyL holder frame I5 in theupwardly extended-position shown in Figures -2A and 3. i .Aself-operating means has thus .been provided to automatically lock, thecopy holder Aframe in the desiredpositionY of extension with noattention fromthe operator who may be extending the copy holder.

. rIhe means for .lock'ng thelineguide memberv 29 in upwardly extendedrelationshipwith respect tothe base I0, 4inifthetproper alignment withrespectyto the plat-en- I4-, includes 'af-separate spring.A pressed -pin'55 slidably mounted in each od.33, 'adjacent the upper end thereof.Thepins 55-55 arez'spring urged into engagement with one or the other ofapair of aligned inclined slotted portions Elie-56,. formed in :oppositesides of each sleeveqBI. k,The pins 155-55. may rbe urged intoengagement v.with the inclined slotted portions 58-56 bygrneansof anelongated springwire 58, secured tonsaid pinV and extending upwardly`through a! drilled portion of therod 3,3 and abutting anedgethereoij'and so inclined with respect to saiddrilledportion ofsaidrod asto continually urge .the pin r55outwa1dly,with respect thereto.Thus, when; the yline guide` member 29 is moved into Athe-upwardlyextended Position shown in Figures Zand 3, the vpins 55-55 will beurgedinto registry with the respective slots SG'f-SS-and-hold said llineguide in an upwardly extended posi- Q fthelnger grip'53."

It should here be understood that the torsion springs I and y63 are bothrelatively strong springs and that the spring 5| snapsthedetent rod 50into engagement with recessed portions 52-52 as soon as said rod vcomesinto registry therewith.v The spring 63 is likewise strong enough'to aid'pivotal movement of the detent rod 50 into engagement with the recesses52-52 and 4cause release of the bifurcated portions'of the feet 6l'-6Ifrom the slots 56-56 with a snap action, ysimultaneous with engagementvof the circumferential portion of the detent bar 50 with the recesses52-52.

It will be understood that modifications and variations may be effectedwithout departing from the spirit and scope of the novel concepts of thepresent invention.
